Borneo Sucker

Species Profile

• Scientific Name: Pseudogastromyzon myersi
• Common Name: Borneo Sucker
• Adult Size: Approximately 3–4 inches (7.5–10 cm)
• Life Expectancy: Around 5–7 years with proper care
• Habitat: Native to fast-flowing streams and rivers in Borneo, often found clinging to rocks in well-oxygenated waters with strong currents and clean substrates

Tank Requirements

• Minimum Tank Size: 20 gallons (75 liters) or larger to accommodate swimming space and current needs
• Ideal Temperature: 72–78°F (22–26°C)
• pH Range: 6.0–7.5
• Water Hardness: Soft to moderately hard (2–12 dGH)
• Temperament: Peaceful but territorial toward its own species and similar bottom dwellers; best kept singly or in very large tanks if multiple individuals are housed

Diet & Nutrition

• Omnivorous: Yes
• Diet: Primarily grazers of algae and biofilm on rocks and surfaces. Accepts algae wafers, blanched vegetables (spinach, zucchini), and occasional protein-based foods like bloodworms or daphnia

Appearance

• Coloration: Brownish body with intricate mottled or spotted patterns that help camouflage against rocky substrates
• Body Shape: Flattened ventral surface with broad pectoral fins adapted for suction and clinging to surfaces in fast currents
• Fins: Large and fan-like, aiding in stability on rocks

Distinctive Features

• Specialized sucker mouth that allows it to cling tightly to rocks in fast currents
• Adapted to high-flow environments, making strong filtration and water movement necessary in captivity
• Small size and peaceful nature make it suitable for well-maintained community tanks with similar flow-loving species
• Unique mottled pattern providing excellent camouflage in its natural habitat
